Mike's suggestion is the best method and the one I would choose. I would
suspect that this would be the method used by a ham that has no problem
drilling a hole in his car to mount a mobile antenna. On the other hand, I'd
be willing to bet that the "extend the element with a bolt" crowd is the
same group that uses a mag mount mobile antenna.
Just an observation. You may disagree.
